Some times The customer wants to see where leak is. I live in the show me state. found multiple leaks with bubbles and detek. when leak is in middle of coil
with dye in system you will have a scenic view for customer to see. Boss bought these new kits and ultra violet light you carry around. It used to be a big light in box you had to retrieve it from shop to use. When you have windy conditions, it is ALMOST impossible to find leaks with sniffers, you need device to hear it or see it

Great post, very informative! I still would never put dye in a system,but that's just my opinion.

So if presented with the challenge of leak searching a refrigeration system for an explosion proof HAZMAT vault where unstable VOC's are stored, how would you proceed?

In this particular situation, attempting to walk into the vault with a heated diode type leak detector would likely get you tackled by a rather large man before you even got to the door, if it didn't get confiscated at the security checkpoint, and infrared sensor type detectors are set off by stuff stored in the vault.

I haven't had much luck with refrigerant dyes. Of course I only used dye a few times 20 years ago. Maybe they're better now, but I have the best luck with an H-10 and soap bubbles...

got an old H-10 that has not been used in years....
are you saying H-10 works better than newest heated diode detectors?

are you using Dawn soap for bubbles?

normally can find leaks with no problems... but got an old R-22 system with a leak that's eating my lunch. normally would not use dyes. but just about ready to for this one. purchased some Cal-Blue LT leak detector. willing to try out just about anything to keep from using dye.

H-10 and Big Blue.

Dtek and a lot of the others aren't up to the Gold Standard that the H-10 set a long time ago.
